Description

Technical Field

[0001] This utility model relates to the technical field of automotive EGR coolers, and specifically to a cooler with a throttling design. Background Technology

[0002] The EGR cooler is a core component of the Exhaust Gas Recirculation (EGR) system, primarily used to reduce exhaust gas temperature and decrease nitrogen oxide emissions. Its working principle involves cooling the high-temperature exhaust gas to approximately 150 degrees Celsius using water or air cooling, thereby improving oxygen mixing efficiency.

[0003] Traditional structural designs typically include inlet and outlet pipes, as well as inlet and outlet water pipes. However, for coolers designed for water cooling, the water circuit design is crucial. The inlet pipe connects to the cooler body to supply cooling water. As the cooling water exchanges heat with the inner core of the cooler body, the temperature of the exhaust gas decreases, while the temperature of the cooling water increases. Therefore, a circulating water design is generally used, resulting in the inlet and outlet water pipes.

[0004] The most common design in current systems is a single inlet pipe supplying cooling water, connected to an outlet pipe to discharge the cooling water. In actual systems, this is circulated by a water pump. However, for this type of product, which is suitable for automotive applications, the water requirements of automobiles are more diverse. A single outlet pipe is no longer sufficient to meet the water needs of automotive parts.

[0005] In order to meet the diverse water needs of automobiles, the cooling water can be supplied to different parts and modules of the car after heat exchange. The distribution of water circuits using pipes of the same diameter results in a huge water consumption. Although the total inlet and outlet water flow rates are the same, the existing structure has different water consumption requirements for each pipe of the same diameter. The excess water consumption in the same water supply is wasted (in traditional pipe design, the pipe flow rate design is based on the idea that it is only necessary to exceed the minimum flow rate requirement). Utility Model Content

[0006] In order to solve the technical problems and shortcomings of the prior art, the present invention provides a cooler with a throttling design, which can overcome the drawbacks of the same water output pipes in the water circuit design of the cooler, and can have multiple branch pipes for selective water connection.

[0007] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0008] A throttling-design cooler includes a shell and a heat exchange core. The heat exchange core is disposed inside the shell and is divided into a water chamber and an air chamber. An air inlet cover and an air outlet cover are connected to both ends of the shell. A water inlet pipe is connected to the bottom of the shell near the air inlet cover and communicates with the water chamber. A water outlet pipe is connected to the top of the shell. A first branch pipe and a second branch pipe are connected to the side wall of the water outlet pipe. The second branch pipe has two sections, and the ends of each section are connected to each other through a throttling pipe bidirectional connector. The two sections of the second branch pipe have the same inner diameter, and the inner diameter of the throttling pipe bidirectional connector is smaller than the inner diameter of the second branch pipe.

[0009] Preferably, the two ends of the bidirectional throttling pipe connector are respectively provided with annular sockets, and the sockets are connected to the second shunt pipe.

[0010] Preferably, the first section of the second diverter tube has a first manifold on its side wall, and the first manifold has an anti-detachment protrusion ring.

[0011] Preferably, the first diversion pipe is horizontal and connected to a spare drain pipe, and a mounting base is fixed on the spare drain pipe for fixing the spare drain pipe.

[0012] Preferably, a second manifold is also provided in the middle of the first diversion pipe, the inner diameter of the second manifold being smaller than that of the first diversion pipe, and the inner diameter of the second diversion pipe being smaller than that of the outlet pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, based on the traditional cooler structure, optimizes the water supply system of the outer shell. First, according to the fixed installation posture of the cooler, the water inlet pipe is set at the bottom of the outer shell to provide cooling water. Then, after the water cools the gas through the heat exchange core, the water temperature rises, and the water will stratify (hot water rises and cold water falls in convection). At this time, the hot water discharged from the outlet pipe can be supplied to different pipes. However, depending on the water usage in the car, the water volume needs to be adjusted. To simplify the structure, firstly, the water volume is reduced by diverting the flow. Secondly, with the same inner diameter of the connecting pipe, the water flow is reduced by connecting the bidirectional connector of the throttling pipe, achieving a double throttling effect.

[0015] 2. The socket design of the bidirectional connector of the throttling tube can improve the assembly firmness;

[0016] 3. The anti-detachment protrusion on the first manifold is to facilitate the connection of the rubber hose and prevent it from falling off;

[0017] 4. The use of a backup drainage pipe further improves the reliability of the operation and makes subsequent maintenance easier and more convenient.

[0018] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0030] Example:

[0031] This invention discloses a cooler with a throttling design, as shown in the following embodiment. Figure 1 and Figure 2 The system includes an outer shell 1 and a heat exchange inner core 2. The heat exchange inner core 2 is disposed inside the outer shell 1 and is divided into a water chamber and an air chamber (the space between the inner walls of the heat exchange inner core 2). The outer shell 1 is connected to an air inlet cover 3 and an air outlet cover 4 at both ends. This structure is a conventional design. The core design point of this solution lies in: Figure 1 In the middle, the bottom of the outer shell 1 is connected to the water inlet pipe 5 near the air inlet cover 3. The water inlet pipe 5 connects to the water cavity (the space between the inner wall of the outer shell 1 and the outer wall of the heat exchange inner core 2). The top of the outer shell 1 is connected to the water outlet pipe 6.

[0032] As can be seen, based on the traditional cooler structure, the water supply system of the outer shell 1 has been optimized. First, according to the fixed installation posture of the cooler, the water inlet pipe 5 is set at the bottom of the outer shell 1 to provide cooling water. Then, after the water cools the gas through the heat exchange core 2, the water temperature rises. As the water temperature rises, it will stratify (hot water rises and cold water falls in convection). At this time, the hot water discharged from the outlet pipe 6 can be supplied to different pipes.

[0033] Combination Figure 3 , Figure 4 and Figure 5As can be seen, the side wall of the outlet pipe 6 is connected to the first diversion pipe 7 and the second diversion pipe 8. This design utilizes the diversion method to reduce the flow rate in each water path.

[0034] The second diversion pipe 8 consists of two sections, each connected at its end by a two-way throttling connector 9. The two sections of the second diversion pipe 8 have the same inner diameter, while the inner diameter of the two-way throttling connector 9 is smaller than that of the second diversion pipe 8. This design utilizes the inner diameter of the two-way throttling connector 9 to further reduce the flow rate, while the inner diameter of the second section of the second diversion pipe 8 remains the same as before. This reduces the water velocity in the second section of the second diversion pipe 8.

[0035] To ensure a secure assembly and a smooth surface, the two ends of the bidirectional throttling connector 9 are respectively provided with annular sockets 91, which are then inserted into the second shunt pipe 8. After the insertion and assembly, the overall surface conforms to the shape of the pipe.

[0036] To further divert the flow, a first manifold 10 is provided on the first side wall of the second diversion pipe 8, and an anti-detachment protruding ring 101 is provided on the first manifold 10. Different rotation options are available for the user. Based on the above design concept, the user can select according to their needs during use, and unnecessary diversion pipes or manifolds can be plugged.

[0037] To further enhance ease of use and reduce cumbersome maintenance and disassembly procedures, the first branch pipe 7 is horizontal and connected to a backup drain pipe 11. A mounting base 12 is fixed to the backup drain pipe 11 for secure fixation. In case of a pipe problem, the pipe can be plugged or shut off, and then the backup drain pipe 11 can be activated.

[0038] Considering the heat loss of hot water during pipeline transmission, excessively long pipelines can easily lower the temperature. Therefore, pipelines with different lengths and flow rates are designed according to users' different temperature requirements. A second manifold 13 is also provided in the middle of the first branch pipe 7. The inner diameter of the second manifold 13 is smaller than that of the first branch pipe 7, and the inner diameter of the second branch pipe 8 is smaller than that of the outlet pipe 6.

[0039] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
